Support matters: A study on genetics and depression

Even people who are genetically prone to depression need help - moreover, they might need it the most.

A recent study looked at how offering support to someone under stress can be especially important if they have a genetic predisposition to depression. 

This research shows that social support can help reduce the risk of developing depression symptoms, particularly for those who are genetically more prone to depression.

How it was discovered

In the study, two different groups were examined: new doctors in their demanding first year of training and older adults who had lost their spouses. 

The researchers used something called a "polygenic risk score" to measure the genetic risk for depression. 

This score is based on what scientists have learned about specific genes that are linked to depression risk.

What they found was that those with a higher genetic risk for depression had a greater chance of developing depression symptoms when they experienced a loss of social support. 

However, when they gained social support during stressful times, their rates of depression were lower.

This study underscores the significance of social support in reducing the risk of depression. 

The researchers hope this information will lead to more targeted support for those who may benefit from it the most.

Why it's important

The key takeaway is that social connections and support from friends and family are essential for well-being, especially when dealing with stress or difficult life events. 

Maintaining or strengthening these connections can help both the person under stress and those offering support. 

Reducing ongoing stress and considering professional mental health help are also important options for those dealing with depression or mental health concerns.
